IPC: F16H7/02
Filed: 2000-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a silent chain driving mechanism where power is transmitted between sprockets having different number of teeth, that is improved in reduction in oscillation and noises by suppressing cordial action of silent chains of both the sprocket having much number of teeth and the sprocket having less number of teeth, also improved in driving performance and durability by suppressing fluctuation of chain tensile sgrength. SOLUTION: An inner side flank tooth surface of a silent chain is expanded compared to an outer side flank tooth surface by amplitude of polygonal movement. Shape of teeth surfaces of a camshaft side sprocket and a crankshaft side sprocket are formed of involute curves which satisfy the formula A1>Ac>=A2, where A1 denotes a pressure angle of the camshaft side sprocket, A2 denotes a pressure angle of the crankshaft side sprocket, Ac denotes a pressure angle of the inner side flank. Cordial action on both crankshaft side and camshaft side can thus be suppressed.

Title: Fixing device
Inventor: KIYOI HIROYUKI
IPC: G05F1/45
Filed: 2000-01-17
Abstract: PROBLEM TO BE SOLVED: To restrain a faulty fixing and temperature rise in a device by restraining a ripple to be small in the control of fixing temperature. SOLUTION: When an optional time has elapsed after the surface temperature of a terminal fixing roller attains the fixing temperature, the maximum value T1 of values equal to or above the fixing temperature and the next minimum value T2 of values equal to or under the fixing temperature, which are paired, are detected as an outputted value before starting the control during the optional time in order to maintain the fixing temperature. Furthermore, plural pairs of the maximum value and the minimum value are obtained to obtain the average of the outputted value.  The averaged value is compared with the fixing temperature by a comparison means and the control is performed so that generated heat quantity per unit time is somewhat increased when (T1+T2+T3+T4)/4 is under the fixing temperature, and the generated heat quantity may be somewhat decreased when (T1+T2+T3+T4)/4 is above the fixing temperature. Thus, the degree of the generated ripple is made smaller and smaller by performing the control that the generated heat quantity per the unit time of a heater is varied.
